🙉 kernel mode rootkits

• https://github.com/f0rb1dd3n/Reptile

  Reptile is a LKM rootkit written for evil purposes that runs on Linux kernel 2.6.x/3.x/4.x

  Feature	Description	Implementation Details
  Environment	2.6.x/3.x/4.x (x86)	sys_call_table search method is x86-only
  Persistency	/etc/modules or /etc/rc.modules	Boot-time module loading using OS-specific startup files.
  Management interface	kill(2)	sys_call_table[__NR_kill]
  Hiding (tampering) of file contents	Filtering while reading	sys_call_table[__NR_read]
  Hiding of files and directories	Filtering of directory entries	sys_call_table[__NR_getdents] sys_call_table[__NR_getdents64]
  Hiding of processes and process trees	Filtering of /proc	Filtering PID-like numeric entries while listing /proc. Hidden tasks are marked using task->flags | 0x10000000. Not able to hide all threads and children of hidden (parent) process.
  Detection evasion	Hides own components	Hide files, unlinks module from module_list, alters contents of startup files while reading.
